To rtf/ whom, innig; {forman-e.: l

Be it known that I, WILLIAM F, Meinem', e citizen of tbe United States, residin at Washington, in tbe District of olunibie, have invented new and useful improvements in Bottle-Stoppers, of which t'ne following isV a specification.

The present invention relates to disk stoppers for milk-bottles and like receptacles, and has for its object to provide e stopper which, while forming a perfect closure for the bottle orY jar, is of such construction that it may be quickly and reediljiY removed from the hottie without the use. of a tool or device for unseeting it and without danger of spilling i or splettering the contents of the bottle durin remove! of the stopper.

n the drawings herewith l have illustrated one embodiment of my invention, sind in seid drawings Figure 1 is e seotionni view of the top or merk of o milk hottie or with the senlingdisk therein, the manner of un sesting the disk being indicated by dotted lines. Fig. .3 is e plein view of' tile sealingdisk. Fig. 3 is e detail view, onlergeig, of tbs tab and body portion to show tbs scoring thepoint of jnnoture. i i

AReferring to tbe drawings by numorsis, 2 indicates the body of the disk, which is of ordinary construction and which may be nisde of any suit-obit: materiel, preferably s. strong cardboard, Projecting from one side of the disk 2 is a, tab 3, preferably formed integrati with the disk 2, seid tab having an aperture 4 formed therein and so united to the disk as to form e substantially U-slia. ed tab projecting from lthe circumferentio. edge of the stopper.

The tab 3 end disk 2 are separated by means of n. snoring 5, wbieh is in iins with or a continuation of the circumferential odge of the disk 2, so that the tab 3 may bc readilyv folded up et right ongles to tbe body portion or disk 2 of the stopper when tbe said disk is forced into the bottle-neck, iis will bv clem' from Fig. Lend tbis sooring is by preference formed on the upper surface of tln stopper, so that the tab 3 Wiiel'i'bcnt up to right-ongle position will not break ofi :it the scoring-line, mid,furtber1nore, the under side of the stop per will present en unbroken surface or skin., so that there will be no point et which the liquid contents of -tbc bottle can attack and soften the iine of juncture between the disk .3

sind tab 3 of the stopper, which would of course result in. weakening the line 0f ettecbment of the tab 3 to the disk 2.

Preferably the aperture 4 is struck ont of the ,teb dong tbe line of juncture of tbe teb end the disk 2, so that its inner mar in is a. continuation of end coincides with tie cir` cnmferential edge of the disk 2, and in its completed :Form the stopper is e substantially U-shaped tob projecting from its edge. The bending up of the tab 3, therefore, may be readily ocoomplisbed, and there will be no breek in the continuity of the circumei'entied odge of the disk 2 which can interfere with conipiete end accurate seating of the disk within the bottle-neck and perfect seniing of bottle.

in toriniog the disk it will be observed that no obi-not ongles are mede et the points of innotni-e of tbe tub 3 and the disk 2, end, for thern'ore, the marginal edv-es of tile aperture ere el! struck on ourveld iines. This fea.- ture find to be a. vnlucbio onefin that the 'tendency o? tbe teb to tesrfroin the disk when snbjeoted to pulling strain is much less than is the esse where the tab sind disk meet on sharp ongles, and the marginal edges of the sperture 4 present angular corners, for obviously en angular corner or point of juncture between the tab and disk would present a. spot et winch the pullin strain would ooncentrete and tearing en separation of the parts naturally take piece. In practice the disk is removed from the bottin by inserting the thumb or finger nail in tbe/aperture in the manner shown in Fig. 1, 'with tbs knuckle of the thumb or finger resting upon tbedisk 2, es shown in seid figure. in this positionthe thumb or finger nots as s lever, so that the edge of the disk carrying the tab can be readily pried out of' its sont with slight exertion, es clearly shown in Fig. l, sind without. danger of tearing the trib from the disk.

isis more that it has been proposed to provide stoppe-rs of the same general character ns the one described above with pull tabs by moons of which they may beV .removed from their seats; but so far Yfis I om swore n tab having en aperture` formed there- I in by ineens of which it may be piled out of its sent by simply inserting the thumb or finger iieii in tbe tab-aperture is novei. Furthermore, in tbe pulbteb Stoppers now 1n use and known to me the tabs have been joined to the body portion ofthe stopper along their entire width, so that when crowded into the seat in the bottle-neck an incomplete sealingr of the bottle results, due to the break in the circumferential edge of the stopper portion proper. In the present construction, however, the legs of the U-shaped tab cause no appreciable break in the stopper edge, so that complete sealing?r is secured.

Having described my invention, I claim-- 1. A bottle-stopper comprisin a body portion, and a pull-tab projecting 'rom the circumferential edge theretf, sald tab having an aperture formed therein to receive the thumb or finger nail.

2.` A bottle-stop per comprising a body portion, and a projecting pull-tab formed integral with said body portion and having an aperture therein to receive the thumb or linger nail.

3. A bottlestopper comprisin a body por` tion, and a pull-tab projecting roln the circumferential edge thereof and having an aperture formed thereinl the inner margin ol" said tab-aperture coinciding with the circumferential ed e of said stopper.

4. A bott e-stopper comprising a boily pol'- tion and a substantially U-shaped tab projectinge,r from the circumferential edge thereof.

5. A bottle-stopper comprisingr a body portion1 and a substantially U shaped tab formed inte ral with said bod portion and projecting rom the circum erential edge thereof 6. A bottle-Stopper comprising a body p0rtion, an integral pull-tab projecting;r from the circumferential ed ge of said body portion and having an aperture therein, the marginal edges of the stopper and tab-aperture beine formed on curved lines and without abrupt angles, whereby the tendency of the parts to tear is eliminated or reducedA In testimony whereof I have hereunto sei my hand in presence of two subscribing wit- HPSSS.
